OIL-BURNER.

Specification of Letters'latent.

Patented Oct. 13, 1914.

Application filed March 22, 1913. Serial No. 756,206.

This invention relates "to an, oil burner," and the principal object of the inventionls to provide a burner which will be very simple in construction, but which will operate very efiiciently for converting the liquid fuel into a vapor.

Another object of the invention is to so construct the burner that the various parts may be easily removed, thus permitting the burner to be easily taken to pieces and put together again.

Another object of the invention is to provide the burner with an improved type of nozzle having the interior provided with spiral threads which cause an air or steam.

jet passing through the nozzle to move with a whirling motion. 4

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanyin drawings :Figure 1 is a side elevation o the burner. Fig. 2 is a longitudinal sectional view throughthe bnrner. Fig. 3 is a top plan view of the burner. Fig. 4 is an end elevation looking into the mouth of the nozzle. Fig. 5 is a perspective View of the nozzle. Fig. 6 is a side elevation of a slightly modified form of burner. i i

This invention comprises a body portion- 10 having its end portions 11 and 12 positioned at substantially right-angles to each other and being also provided with a neck 13 positioned in alinement with the end 12.

The end portions 11 and 12 as well as the neck 13 are internally threaded to permit various parts to be hereinafter mentioned to be removably connected with the body portion.

The fuel inlet pipe 14 is provided with a threaded section 15 by means of which the inlet pipe may be removably connectedwith a bushing 16 threaded into the neck 13, and

is provided wit-h an enlarged threadedouter end portion 17 by means of which a pipe leadingfrom the reservoir. not shown may i be removably connected with the fuel inlet pipe. The inner portion 18 0f. the fuel inlet pipe isreduced as shown .in: Fig. 2;. andis provided with a tapered end portion 19 in which, a small outletopening 20 is formed.

It should be'rnoted that the inner port-ion 18 1 and outer portion 17jmay be formed integral? with the intermediate portion 14 or may be fo rmedffromseparate pieces of metal piping and threaded into or upon the interme diate sectionv 14. y 1

The tapered nozzle 21 has the walls of its central opening 22 provided with grooves 23 similar to the rifling in a. rifle barrel, thus causing the air passing through the nozzle to move with a whirling motion. A nipple 24 iscarried by the inner end portion of the tapered nozzle and passes through a reducer 25 threaded into the threaded neck 12. F ro-rn an inspection of Fig. 2 it will be readily seen that the pipe 18 does not pass through the center of the nipple 24 and nozzle 21, but passes above the center so that the stream of oil whichv passes out through the opening 20 will be directed close to the grooves 23, thus causing this stream of oilto be directed into that portion of the air current which has the greatest whirling motion. It should also be noted that by this construction if the oil feeds too'freely it will have a greater distance to drop before striking the lower portion of the nozzle and, therefore, the whirling air-current will have gigeater opportunity to break up the stream 0 oil.

In Fig. 6 there has been shown a slightly modified form of burner in which the nozzle 26 is of greater length than the nozzle 21 and is provided with a threaded end portion pipe18 in the nozzle may be regulated. By

this arrangement the length of time it takes for the mixed air and oil to pass out of the nozzle may be regulated.

When using this device it is set up as shown in Figs. 2 or 6, and the pipe leading from the oil supply tank is connected with the outer end portion 17 of the pipe '18, thus causing the oil to be fed into this pipe and pass out through the opening 20 in its inner end. Air or steam is admitted through a suitable pipe leading into the neck 11 from a suitable reservoir and passes through the nozzle 21 Where it is caused to have a Whirlair andioil to be regulated.

Having thus described the invention What is claimed as new, is

In an oil burner, a casing havin a fuel pipe opening, an atomizing fluid lnlet at right angles thereto, a tapering nozzle having an adjustable connection With said casing, the bore of said nozzle having spiral grooves thereon, and a fuel pipe extending 25 eccentrically through said casing and nozzle and terminating adjacent said spiral grooves.

In testimony whereof I hereunto afiix my signature in presence of two Witnesses.
